To protect your network from unwanted entries and from restricting the users to access your private files and documents, you can create a Guest network in your dlinkrouter.local device. A Guest network provides a medium for guest users to access the Internet without accessing the resources from the main network. You can configure this network through the web interface of the router and can also assign a particular Wifi band i.e 2.4 GHZ or 5GHz to the Guest network.https://dlinkrouterlocall.ca/
